Vaadin Framework 7.7.49

The Vaadin Framework 7.7.49 is an extended-support release with the following changes:

• Made loading of scripts happen synchronously like in Vaadin 8
• Added support for the usage of multiple @JavaScript and @StyleSheet annotations on a class
• Bumped Atmosphere version to fix a potential NPE issue
• Fixed internal Atmosphere version check to correctly detect MPR/Jakarta version of Push
• Updated license checker invocations to be compatible with upstream technical licensing changes.

Vaadin Framework 8.28.4

Vaadin Framework 8.28.4 is an Extended Maintenance update release with the following changes:

• Fixed critical issue in license checking which became evident with 8.28.3 during the release. While the 8.28.3 release artifacts are available, build announcements were held back due to this issue. This release restores old behavior.
• Fixed a NullPointerException in Push (Atmosphere) where a missing null check in a logging call would create a mystery stack trace on the server when attempting to communicate with an already disconnected client. This is likely the fix to an issue reported in Flow.
• Fixed the Push version check to not complain about vaadin-push-jakarta.
• Fixed an issue where getBeanPropertyDescriptors() could include
  properties more than once in the returned results list.
  This is a backport of Flow PR #21836.
• Updated license checker for improved compatibility.

Vaadin Framework 7.7.48

The Vaadin Framework 7.7.48 is an extended-support release with the following changes:

• Updated to Atmosphere 2.4.x, and consequently, Java 8. This bumps the minimum Java requirement from 7 to 8.
• Added changes to make interrupting uploads more reliable, and block a possible security issue in the process.

Vaadin Framework 8.28.2

Vaadin Framework 8.28.2 is an Extended Maintenance hotfix release with the following changes:

• Fixed a bug where scrolling in a UI with a menubar would attempt to close the menubar popup even when the popup didn't exist, resulting in a cascade of JavaScript errors in the console.
• Improved Upload component handling so that the receiveUpload handler will not get triggered if the upload has been interrupted in startListener.
• Updated the JNA and OSHI dependencies for security.

Vaadin Framework 8.28.1

Vaadin Framework 8.28.1 is an Extended Maintenance hotfix release with the following change:

• The Grid fix in 8.28.0 that made sure that DOM contents are not altered unless there is a need to update them was missing the logic for the Vaadin 8 version of Grid's TextRenderer, while it was added for the Vaadin 7 compatibility Grid. This hotfix version adds the TextRenderer logic to the Vaadin 8 Grid.

Vaadin Framework 8.28.0

Vaadin Framework 8.28.0 is an Extended Maintenance release with the following changes:

• Fixed a Grid issue that was affecting at least Firefox where attempts to copy and paste text became difficult or impossible due to how Grid handled cell value updates during a refresh. Cells are refreshed every time a cell is clicked.

• Fixed a MenuBar issue where the popup menu would become detached from the MenuBar and possibly inaccessible if the browser window was resized or scrolled. The popup menu will now be closed if a resize or mousewheel event is detected.

• Improved Grid accessibility regarding navigation.
  A new accessible navigation mode is introduced which changes Grid focus handling and DOM properties such that NVDA and similar screen readers will correctly announce current cell contents, allow proper tab navigation, properly reacts to header rows and adjusts the handling of the focus visuals to match.
  This new functionality can be toggled on and off using the API Grid.setAccessibleNavigation(boolean) and the status checked using Grid.isAccessibleNavigation().

• Fixed Combobox behavior so that the aria-expanded property is correctly handled when the combobox dropdown is opened and closed. This fixes combobox related issues with screen readers.

Vaadin Framework 7.7.47

The Vaadin Framework 7.7.47 is an extended-support release with the following changes:

• Fixed the text selection problems within Grid cells, so copying the contents of a single cell is possible
• Added a Jakarta-compatible Push module
• Fixed root module POM Source Code Management URLs to point to the correct repository

Vaadin Framework 7.7.46

The Vaadin Framework 7.7.46 is an extended-support release with the following changes:

• Updated the Maven plugin to get rid of dependencies with known vulnerabilities

Note: Vaadin 7 projects require Java 8 when doing development builds, production mode builds will still work with Java 7. This is due to updates in the license checker, which internally is using Java 8

Vaadin Framework 8.27.7

Vaadin Framework 8.27.7 is an Extended Maintenance patch release with the following changes:

• Major update to Vaadin Maven Plugin to avoid depending on obsolete packages with open CVEs. While none of the affected packages have presented an actual risk to users due to how they were used within the Vaadin build process, they were being flagged as security issues, and as such were undesireable to have in the dependency list.
• Fixed an issue where the SessionDestroyListener would receive a null WrappedSession instance and thus the HTTP session could not be explicitly invalidated.
  This is a backport from Flow. See Flow issue #6959.
• Fixed Grid's sorting indicator visibility when using the Runo theme.

Vaadin Framework 7.7.45

The Vaadin Framework 7.7.45 is an extended-support release with the following changes:

• Set no-store headers for error responses
• ComboBox popup size and positioning take into account the menu element’s own padding in addition to the menu item’s
• Internal changes, and a fix for a license checking issue
